chengyongru 43bd8aac8d fix(msteams): harden availability check and migrate docs to README
- Check both jwt and cryptography in MSTEAMS_AVAILABLE guard so
  partial installs fail early with a clear message instead of at runtime
- Add aclose() to test FakeHttpClient so stop() won't crash
- Move MSTEAMS.md into README.md following the same details/summary
  pattern used by every other channel
- Note in README that validateInboundAuth defaults to false
